Abstract

When developing a system for the home automation Assys we expand the functionality and complexity of the system and with that we achieved the highest capability of microcontroller ATmega328P. In this thesis we described the properties of the platform which prevent the further development and reasons for the need for more capable microcontroller. The study was carried out on the development board STM32F4 Discovery, which contains a powerful microcontroller from the family ARM Cortex-M4. On the new platform, we implemented part of the system which is responsible for dimming and with that we directly demonstrated the benefits of more powerful hardware. In the study, we found out that the replacement of the microcontroller is necessary despite the higher price, power consumption and additional costs during the transition. If we consider the gained performance of the new platform the replacement is justified.
